malnutrition

In 2013, Maastrich University researchers announced that they had created a hamburger made completely out of beef grown in a lab. Mark Post, one of those Dutch professors, recently estimated on an interview with ABC news that the cost to make a lab grown burger has dropped to $11 a patty, or about $80 per kilogram. (Wagyu beef costs $33/ounce. Kobe beef costs $200 a pound.) The burger is made by incubating calf muscle stem cells in a nutrient of fetal calf serum.
